That is not how a true scientist thinks. Effects are not necessarily linear. For example, in order to see some effects in quantum mechanics, a threshold must be passed. Or in physics, a certain amount of force to overcome the minimum threshold as a result of friction.

Problem solving isn't such a simple operation. One must be careful with logic.

See my other post. You are not entitled to simply leap to the conclusion that because we did not see a predicted effect, that we must have simply not reached the threshold. There is still the distinct possibility that we're entirely wrong about what will happen if we increase the input.

Basically, everybody here is not thinking with their science hats. They are thinking with their social engineering/political hats, where a government action to forcibly reduce working hours simply must have positive benefits, essentially axiomatically, and if we're not seeing them yet we must simply not be trying hard enough yet, a classic social engineering mindset. But that's not a scientific mindset. There's no guarantee this intervention must have positive results. There's no guarantee the axiom is actually true.
